Case Study: ListingSpark accelerates list-to-close, boosts NPS and drives $500M in transactions with Dropbox Sign

ListingSpark Delivers $500 Million in Real Estate Transactions in First Five Years

ListingSpark is a tech-driven real estate platform that helps homeowners sell faster and keep about 3% of the sale (roughly $7,200 on average). Launched after the 2008–2010 downturn, the company needed a fully integrated, mobile-friendly eSignature and document workflow so sellers could complete multi-page forms in one browser window—avoiding the churn and disconnected experience caused by third‑party signing platforms.

ListingSpark implemented the HelloSign API for embedded signing, editable templates, auto-fill and a robust audit trail. The result: a 28% faster list-to-close time, listings on the MLS in about 10 minutes, signed offers in under a day in some cases, a Net Promoter Score of 71, dramatically fewer disputes, improved operational productivity, and $500 million in transactions in its first five years.
